Abstract:
Provided is a vibration wave motor including: a vibrator; a friction member configured to be brought into frictional contact with the vibrator; a first holding member holding the vibrator; a second holding member holding the first holding member; and a third holding member holding the second holding member, wherein the vibrator and the friction member move relative to each other, and wherein one side of the second holding member is configured to connect to the first holding member or the third holding member at a position where the second holding member overlaps the rectangular shape portion in a direction of the relative movement, and another side of the second holding member is configured to connect to the first holding member or the third holding member at a position where the second holding member overlaps the rectangular shape portion in a direction perpendicular to the direction of the relative movement.
